DREDGlN G-BUCKET.

SPECIFICATION forming part of Letters Patent No. 499,451, dated J une13, 1893.

A Application filed January 11, 1893- Serial No. 457,985. (N model.)

- To all whom it may concern:

Be it known that I, WILLIAM A. COLLINS, a citizen of the United States,and a resident of Bayonne, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inDredging-Buckets, of which the following is a specification.

This invention relates to certain new and useful improvements indredgingbuckets, and has for its object the production of such a bucket in whichthe swinging door, forming the back of the bucket during the dredgingoperation, and the bottom of the bucket when the latteris raised, andtilted to its unloading or dumping position, may be positively andsecurely caught and held in its closed position, and which may bereadily and easily unlocked and left free to swing away from the bucket,when the latter is in its position for unloading or dumping.

To these ends my invention consists in a dredging bucket havingaswinging door held in its closed position by a latch mounted uponanti-friction rollers, and means for moving said latch out of engagementwith said bucket, all as hereinafter more fully described and pointedout in the claims.

In the accompanying drawings illustratingmy invention, in both thefigures of which like parts are similarly designated, Figure 1, is arear elevation, and Fig. 2, is a fragmentary side elevation, partly insection, of a bucket embodying my invention.

A, represents the bucket, the bottom of which at its rear, is providedwith the bolt or latch hold B, preferably reinforced by the keeper 0, inwhich is dovetailed the steel piece 0', and provided with the curvedprojecting tongue D.

E, is the swinging side or door, hinged to bucket A, by the hinge stripsF, and provided upon its inner face with the open ended latch chamber G,within which the lock or latch H, is located and retained by the eye, orperforated lug I, passing through a slot or elongated opening J, in doorE, and screwed into the latch H, which isproperly tapped andscrew-threaded to receive it. The latch H, as shown, is beveled orcurved inwardly, preferably at both ends, and as illustrated in Fig. 2,is provided with the elongated slots h, h, within which are mounted theanti-friction wheels or, rollers K, K, of 'a diameter greater than thelatch and slightly less than the width of the'latch chamber G. Ifdesired, 5 5

the rollers K, K, may be mounted upon the fixed axes as shown, or thelatch G, may be provided with lateral elongated slots, within which therespective ends of the axes may be held, and be free to move as thelatch is op- The operation of myimproved device is as follows, assumingthe parts to be in the position shown inthe drawings: The bucket islowered and scoops up the mud, rock or other I substance and is thenraised and tilted in the usual way until the swinging door E, forms thebottom of the bucket. The rod L, is then manipulated through the togglelever and rope (not shown) drawing inboard the eye I, and with it thelatch H, which without regard to the weight'of the material in thebucket runs easily upon its anti-friction rollers K, K, releasing latchH, from the slot or bolt hole B, keeper 0, and piece 0, and the door Eby gravity and the weight of the material it is sustaining swings uponits hinges downwardly and away from the bucket A, dropping or dumpingthe load. As the bucket A, assumes its dredging position, the latch H,will drop by gravity and project beyond the door E, and as said doorassumes its closed 0 position, the beveled or rounded end-of latch H isengaged by the projecting tongue D, lifting the latch into its chamberG, until the door E, has reached its most inward position,

when said latch again drops, and engages in 5 the latch hole B, securelyholding and retaining the door E, in closed relation to the bucket. Asbefore described, I prefer to round off or bevel both ends of latch H,so that when one end becomes worn, the latch may be removed from itschamber and reversed.

What I claim as new, and desire to secure by Letters Patent, iso 1. Adredging bucket having a swinging The upper end of this rod is con- 65side or door carrying alatch chamber, alatch mounted upon anti-frictionrollers working in said chamber and adapted to engage with anappropriate latch hole in said bucket; and means, substantially asdescribed for manipw' lating said latch and retaining the same witl1- inits chamber, substantially as described for the purposes set forth.

2. A latch for the swinging doors of dredging buckets comprising a solidbar, the ends of which are oppositely beveled or chamfered, providedwith longitudinal openings of a size to admit anti-friction rollers, andanti-friction rollers mounted to said latch, and within said openings,substantially as described for the purposes set forth.

3. A latch for the swinging'doors of dredging buckets working within achamber upon said door, said latch comprising a solid bar, the ends ofwhich are oppositely beveled or chamfered, provided with longitudinalopenings of a size to admit anti-friction rollers, and anti-frictionrollers greater in diameter than the latch and less than the width ofthe latch chamber, mounted to said latch Within said openingssubstantially as described for the purposes set forth.

Signed at New York, in the county of New York and State of New York,this 10th day of January, A. D. 1893.
